Manes

From publisher blurb:

The Stuff of Nightmares

The Manes (pronounced “Mah-nez”) are a race of vampiric shapeshifters who are feared across the known galaxy. For thousands of solar cycles, the Manes were contained within the G’henna Star Cluster by the Astral Knights.

That all changed ten solar cycles ago, when the Manes created a great dreadnaught and used it to destroy the Astral Knights. The Manes were able to escape from G’henna and scatter across the Milky Way Galaxy.

Vampiric by nature, Manes subsist on a diet of blood. Manes transform to mimic the appearance of any creature whose blood they have tasted.

Iconic Legends. Because sometimes you a need a character everyone knows, even if they're meeting them for the first time.
